ABSTRACT:
Providing a multicast service to a mobile node includes receiving a first request to join a multicast group from a first cell site. The first request requests that a first mobile node be permitted to join the multicast group. A first multicast source operable to provide content to the first mobile node is identified. The multicast group and the first multicast source are associated to yield a first group-source combination. A first key is assigned to the first group-source combination, and the first key is provided to the first cell site.
